CAR-LOADER.

SPECIFICATION forming part of Letters Patent No. 679,048, dated July 23,1901.

Application filed March 30, 1901. $erial No. 53,625. (No model.)

To all whom it may concern:

Be it known that I, CHARLES D. COLE, a citizen of the United States,residing at Sullivan, in the county of Moultrie and State of Illinois,have invented certain new and useful Improvements in Oar-Loaders, ofwhich the following is a specification.

My invention has relation to car-loaders; and it consists of the novelconstruction and arrangement of its parts as hereinafter described.

The object of my invention is to provide a means for rapidly loadingcars with grain, the device being so constructed as not to crack orsplit the grain during the process of loading. The loader is constructedon substantially the same principles as an ordinary suction air-fan.Thegrain is introduced at the center of the fan and is thrown off bycentrifugal force at the ends of the blades and discharged throughsuitable openings in the rim into the car.

In the accompanying drawings, Figure l is a transverse sectional View ofthe loader. Fig. 2 is a top plan view of the loader with the upper partremoved.

The loader consists of the casing 1 made in two parts and containing thedischargespouts 2 2. Theinlet-port 3 enters the upper part of the casingl at the center thereof.

The upper and lower-parts of the casing 1 are suitably bolted together,and a revolving spider 4 is located Within the casing. In the center ofthe lower half of the casing is prothe top of the inlet-spout 3 for thereception of the box 6. These boxes receive in a vertical position theshaft 7, to which is fixed the spider 4. A pulley-wheel 8 is attached tothe lower end of said shaft. The spider 4 is provided with afrusto-pyramidal-shaped hub 9, from which extend the flights or blades10. The spider is constructed in such shape that the action upon thegrain is dilferent from a spider having flights of a square ortriangular shape and projecting from the hub in a straight line. Thespider may be constructed with any number of flights, the numberrequired being determined by the diameter of the spider. The hub 9extends above the point at which the flights are joined on,

and the outer surface of said hub is made up of a series of flatsurfaces, one above each flight, as shown in Fig. 2. This form of hubacts as a force-feed, having a tendency to force the grain from thecenter of the loader to the ends of the flights.

As shown in Fig. 1, the flights are as wide:

at their outer ends as the casing will permit to prevent the grain fromriding over, and insures the delivery of a full load for each flight. Asshown in Fig. 2, the faces of the flights present two angles to thegrain. This construction is such that as the grain flows into the loaderit is immediately forced to the ends of the flights. As an illustration,should the spider be removed and a flat circular disk. be substituted,if the disk be revolved rapidly the grain when falling upon it would byforce of the centrifugal action seek the outer edge of the disk, butsufficient force would not be secured to throw the grain in asatisfactory manner through the discharge-openings. To secure thisforce, it is necessary to provide flights or blades to assist indischarging the grain. These flights as usually constructed and whenrevolving rapidly act as a damper and to a certain extent confine thegrain in the center of the loader, thereby reducing the capacity of theloader. The inner ends of the flights are cut away, as shown in Fig. 1,for the purpose of facilitating the entry of the grain to the interiorof the casing 1.

, In operation the loader is supported just within the car-door bybrackets, (preferably of the folding type.) A spout leading from thegrain-bin to the inlet-port 3 conveys the grain from the bin to the saidport. The grain then flows through the opening in the casing into theinterior of the loader. The spider having a rotary motion, the grain iscarried around by the flights until the first discharge-opening isreached, through which it passes into the car. If desired, short metalspouts (not shown) may be placed over the discharge-openings and may beso adjusted, up or' down, to discharge the grain high or low, asdesired; also, sliding gates may be provided at the inlet-port, ifdesired. The boxes which carry the shaft may be detachable and may allowof a vertical adjustment of the shaft. Power may be secured by the useof a pulley, as shown, or rope-transmission sprocket-wheel and chain orelectric motor attached to the bottom of the casing may be employed forrevolving the spider without departing from the spirit of the invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. A loader comprising a casing having in the center of its top aninlet-port and in its sides discharge-openings, a revolving spiderlocated within the casing, the outer ends of the flights of said spiderbeing as wide as the casing will permit, the inner and upper edges ofthe spider being cut away, said spider having a frusto-pyramidal hub.

2. A loader comprising a casing having in the center of its top aninlet-port and in its sides discharge-openings, a revolving spiderlocated Within the casing, the outer ends of the flights of said spiderbeing as Wide as the casing will permit, the inner and upper edges ofthe spider being cut away, said spider having a frusto-pyramidal hub,the upper end of which extends above the inner ends of the flights.

3. A loader comprising a casing having in the center of its top aninlet-port and in its sides discharge-openings, a revolving spiderlocated within the casing, said spider having flights, the innerportions of the said flights being tangential with relation to an outercircumference of the hub, and the outer portions of the said flightsbeing tangential with relation to an inner circumference of the hub, thefront faces of the flights forming two planes at an obtuse angle to eachother.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES D. COLE.
